Rearview Mirror

The rear-view mirror is one of the main devices found in cars. A mirror is a mirror used to see the traffic of a vehicle behind when it is about to veer, stop or change lanes. The purpose of this study was to design a pre-crash performance test of the rearview mirror. That is a system that will automatically perform mirror folding automatically based on the distance of the object in front of it. The system will reduce the risk of broken or scratched due to driver negligence. The research method at a time when the barrier is 30cm (±20cm) away from the front or back of the rearview mirror will read that distance which will then transmit to the Arduino. Arduino will process the data and send data for the speed reduction process by warning that there is an object in front or behind the rearview mirror and when the distance is <30cm from the barrier object, then the Arduino will order to fold the rearview mirror automatically, by activating the servo motor to fold the rear and rearview mirrors. The result of this study was to find out the performance of the GP2Y0A21 distance sensor reading and the performance of the rearview mirror pre-crash system. In this study, the bound variable was the distance measurement of the sensor's reading. The free variable used is the sensor reading metering distance displayed on the LCD (Liquid Crystal Display).

Canna (Canna edulis Kerr.) is a type of tuber plant with a fairly high starch content to be used as food. The use of canna is generally processed first into flour. The initial process of flouring canna is done in two ways; the canna plants are sliced and grated. The Department of Agricultural and Biosystem Engineering, Faculty of Agricultural Industrial Technology, University of Padjadjaran, designed the TEP-1902 Canna Slicing and Shredding Machine (MPPG). However, the performance of this machine was not yet known, so testing was needed to determine its performance. The research method used was an experimental method that was analyzed descriptively by measuring, observing, calculating, analyzing, testing, and evaluating the TEP-1902 Canna Slicing and Shredding Machine (MPPG). The results of the performance test of this machine showed that the machine's performance was good, with the following parameters: the actual capacity of the slicing unit and grating unit was 40.95 kg/hour and 182.98 kg/hour, respectively, efficiency was 92.61% slicing and 97.60% grater, the yields were 98.75% slicing and 96.50% grating, respectively, the average thickness of the slices was 2.13 mm, and the uniformity of slice thickness was 65.51%.

Abstract--A manual door security system that has many shortcomings including difficulty opening locks when used, easily broken and keys that tend to be duplicated thereby reducing convenience and security. To prevent this, a good and easy-to-use room security system is needed. At this time began to develop an electronic room safety system using RFID technology (Radio-Frequency Identification) to improve the security system at the door of the house. In this study discusses the design and prototype of an automatic room door lock using an RFID system. The research method used is research and development. This Automatic Door is programmed by the Arduino application by creating a security system using Radio Frequency Identification (RFID) as a radio wave of data carrier frequencies that will be received by the receiver. The results of this study are the creation of an automatic home door security system using RFID which has a better level of security compared to manual security, so that it can cope with acts of theft in homes that are often abandoned by residents. In addition, the use of RFID can also minimize the overall lock on the house, so that every family member needs only one tag card / key to open all the locks on the door in the house.

Home security is something that must be considered for every homeowner. Especially when you have to leave the house empty for work or even on vacation. You must be worried about thieves, lost jewelry, or the safety of other valuables. Therefore, the authors made a door lock security device by utilizing a Bluetooth connection with the Arduino Uno microcontroller. The research method used was direct observation of the selected object, namely the author's house, and conducting literature studies related to the Arduino Uno microcontroller. This door lock tool uses the Arduino Uno as a data processing center, because it is easy to use, and most importantly in the charging program, it does not require a download like a microcontroller in general. This Arduino Uno contains a special program that will give commands to the Servo Motor to open and open the door. Not only opening and opening doors, but this tool can also move the door without us holding or touching it but through a Smartphone. The purpose of this research is to produce a tool that can make it easier to manage or open doors using the Arduino via an Android smartphone using a Bluetooth connection.
